- 論文の詳細を見る
Electron transport of interacting electrons in a quantum wire is investigated. The resistance is calculated in the lowest order in the impurity potential taking account of the electron-electron interaction in the form of the vertex correction to the interaction with the impurities. To calculate the vertices we use the parquet diagram method, and the results by the renormalization group method on the transmission of single barrier are reproduced in the lowest order in the impurity potential. The case of coulomb interaction is investigated also and it is pointed out that the temperature dependence of the resistance is qualitatively equal to that for short-range interaction.
